Answer:
8.8 inches
Step-by-step explanation:
Since the level is proportional to the time, when the time increases from 5 to 11 (by a factor of 11/5), we expect the water level to increase by a factor of 11/5 to ...
(4 in) · 11/5 = 44/5 in = 8 4/5 in
Slope of line l (m1)=5
Slope of line w(m2)=-1/5
Since,m1×m2=-1 , line 'l' and 'w' are perpendicular.
Since line 'k' doesn't intersect line 'l' ,they must be parallel b'coz they are in the same plane as well.
Here, 'l' is perpendicular to 'w' and parallel to 'k'....so w and k must be perpendicular to each other.
It can be proven:
Since l and k are parallel, their slopes are equal.
So, slope of k (m3)=5
Since m3×m2=-1 ,w and k are perpendicular.
Hence, angle between w and k is 90°
